    like compare all the color with a for

    you said it to me ^^

    @Payx
    No. use a list (of colors) and loop over it, checking each.

    i already have this (you give it to me)

    QMap<QRgb, CostInfo > Costs = {
    	{ QColor(255 , 0 , 0 ).rgb(), { "://fraise.png", 10 }},
    	{ QColor(0 , 255 , 0 ).rgb(), { "://balleverte.png", 20 }},
    	{ QColor(0 , 0 , 255 ).rgb(), { "://ballebleue.png", 20 }},
    	{ QColor(255 , 255 , 255 ).rgb(), { "://balleblanche.png", 20 }},
    	{ QColor(255 , 128 , 0 ).rgb(), { "://ballepeche.png", 20 }},
    	{ QColor(0 , 0 , 0 ).rgb(), { "://noir.png", 20 }},
    	{ QColor(102 , 51 , 0 ).rgb(), { "://marron.png", 20 }},
    	{ QColor(255 , 102 , 78 ).rgb(), { "://rose.png", 20 }},
    	{ QColor(0 , 204 , 204 ).rgb(), { "://turquoise.png", 20 }},
    	{ QColor(255 , 178 , 102 ).rgb(), { "://beige.png", 20 }},
    	{ QColor(76 , 0 , 153 ).rgb(), { "://violet.png", 20 }},
    	{ QColor(100 , 100 , 100 ).rgb(), { "://gris.png", 20 }},
    };
    
    bool IsCloseColor( QColor c1, QColor c2 ) {
    	int diffRed   = Math.abs(c1.red() - c2.red());
    	int diffGreen = Math.abs(c1.green() - c2.green());
    	int diffBlue  = Math.abs(c1.blue()  - c2.blue());
    
    	if (diffBlue+diffRed+diffGreen< 100){	/
    		return true;.
    		else
    				return false;
    
    
    	}
    }
    

    the function i want to create is to browse the Qmap and pick the color who got the minimum ""diffBlue+diffRed+diffGreen< 100""

      Hi
      ok. i see. we had the code higher up.

      Qcolor colour; // the one you compare too. set to something...
      QMapIterator<QRgb, CostInfo >i(Costs);
      while (i.hasNext()) {
      i.next();
      QColor BaseColor( i.key() ); // the color in table
      if (Costs.contains( colour.rgb() ) || IsCloseColor(BaseColor, colour) ) { // directly have colour or it is < 100
      //// we got a match
      }
      }// while

        Okay,

        but we keep the code ?

        because the <100 isn't good, you said we have to compare all the colors and see what colors match the best

          Yes ?
          Then change the 100.
          Its just a value. You should examine your color and see
          the value for color that you consider "The same"
          Maybe its need to be 80 or 110. Depends on how close
          the color must be for you to think its the same.

            Yes, but correct me if i'm wrong, it could be possible that it detect many colors under 100 right ?

              @Payx
              its a value. How high or low u need it to be , depends
              on your application.

                yes but i can't know exactly, thats why i put 100.

                The things i want its the minimum of all the value

                like a function who calcule all diffBlue+diffRed+diffGreen
                and return me the minimum

                    Maybe you use it above where you define it or maybe u didnt show it how CostInfo is defined.

                      I defined my QMap here :

                      QMap<QRgb, CostInfo > Costs = {

                      	{ QColor(76 , 0 , 153 ).rgb(), { "://violet.png", 20 }},
                      	{ QColor(100 , 100 , 100 ).rgb(), { "://gris.png", 20 }},
                      };
                      

                      And this is a function call no ?

                      QMapIterator<QRgb, CostInfo>i;

                            the compiler only knows the fundamental types or types defined.
                            so you need to define CostInfo or compiler will give you an error.

                                in your case, one of the value you give is { "://fraise.png", 10 }, which is composed of a string and a integer

                                it seems CostInfo should look like this

                                struct CostInfo
                                {
                                  QString imageName;
                                  int     cost;
                                };

                                  Okay understood how it works now.

                                  Why it say that "Costs" is not declared, it is the name of the QMap right ?

                                      i tried

                                      QMap<QRgb, CostInfo > Costs;

                                        Yes that is how you declare an empty QMap called Costs.
